我正在尝试开发一个Android应用程序，该应用程序将播放视频然后转换到另一个活动。
我遇到的问题是视频需要播放FullScreen，为了做到这一点，我必须切换来自＆＃34; AppCompatActivity＆＃34;到＆＃34;活动＆＃34;否则程序会在尝试全屏运行时崩溃。
因此，当我转换到下一个活动时，我必须使用extends Activity调用该类。 现在，当我尝试实现抽屉侧边栏时，我遇到了问题，因为该课程没有扩展AppCompat，并且明显存在＆＃34; getSupportActionBar＆＃34;
（视频播放，并转换到第二个屏幕而不会发出它只是从那里开始我已经被抓住了）
有没有办法让我的第二个活动扩展AppCompat，而不会崩溃？或者，如果有人知道更有效的实现方法吗？
public class Main extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.act_main);
VideoView splash = (VideoView) findViewById(R.id.SplashView);
Uri splashPath = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.phsplash);
splash.setVideoURI(splashPath);
splash.start();
final int interval = 7000;
Handler handler = new Handler();
Runnable runnable = new Runnable(){
public void run(){
Intent goHome = new Intent(Main.this, HomeView.class);
startActivity(goHome);
}
};
handler.postAtTime(runnable, System.currentTimeMillis()+interval);
handler.postDelayed(runnable, interval);
}
}
XML
<VideoView
android:id="@+id/SplashView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
然后是Home视图（由于AppCompat问题而没有写完）
public class HomeView extends Activity {
private ListView theDrawer;
private ArrayAdapter<String> theAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
theDrawer = (ListView)findViewById(R.id.drawlayout);
theOptions();
setupDrawer();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
private void theOptions(){
String[] panelarray = {"About PHam", "Upcoming Projects", "Idea Submit", "Locate PHam"};
theAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, panelarray);
theDrawer.setAdapter(theAdapter);
theDrawer.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
Toast.makeText(HomeView.this, "WTF is Toast!", Toast.LENGTH_SHORT).show();
}
});
}
private void setupDrawer(){
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="This is the Home Screen!"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/textView" />
<ListView
android:id="@+id/navlist"
android:layout_width="200dp"
android:layout_gravity="left|start"
android:layout_height="match_parent"
android:background="#ffeeeeee" />
</LinearLayout>
然后最后清单
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.phsplash.captain.pcketham">
<application
android:allowBackup="true"
android:icon="@mipmap/phico"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<activity android:name=".Main">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".HomeView"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black" >
</activity>
</application>
</manifest>

答案 0 :(得分：3)
从 AppCompatActivity 而不是活动扩展您的第二堂课。
public class HomeView extends AppCompatActivity
快乐的编码。干杯！
修改
对于那些只是低估了我的答案的伟大，这里是一段代码片段而没有来自Android Studio的任何错误：
public class test extends AppCompatActivity{
private ListView theDrawer;
private ArrayAdapter<String> theAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
}
以下是有关支持操作栏的必要文档的link。
答案 1 :(得分：1)
要解决 appCompat 错误，您需要将支持库添加到您的app build.gradle依赖项：
compile 'com.android.support:appcompat-v7:24.2.0'
请务必使用相同的API版本调整androidBuildToolsVersion，androidCompileSdkVersion和androidTargetSdkVersion。在这种情况下，您需要使用API Level 24。
然后，您可以使用Activity扩展您的AppCompatActivity，例如：
public class HomeView extends AppCompatActivity {
...
}
从支持资料库了解详情：
<强>更新
根据您的错误日志，这意味着您需要使用AppCompat作为您活动的主题。使用AppCompat更改styles.xml资源，如下所示：
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item> <!-- Your primary color -->
<item name="colorPrimaryDark">@color/colorPrimaryDark</item> <!-- Your dark color -->
<item name="colorAccent">@color/colorAccent</item> <!-- your accent color -->
</style>
然后将主题添加到 AndroidManifest.xml 中的活动或应用程序，其中android:theme="@style/AppTheme"为：
<application
android:allowBackup="true"
android:icon="@mipmap/phico"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
